Zusammenfassung: | Energy and Buildings 29, 3 (1999) 283-292 The calculation of airflows is of great importance for detailed building
thermal simulation computer codes, these airflows most frequently constituting
an important thermal coupling between the building and the outside on one hand,
and the different thermal zones on the other. The driving effects of air
movement, which are the wind and the thermal buoyancy, are briefly outlined and
we look closely at their coupling in the case of buildings, by exploring the
difficulties associated with large openings. Some numerical problems tied to
the resolving of the non-linear system established are also covered. Part of a
detailled simulation software (CODYRUN), the numerical implementation of this
airflow model is explained, insisting on data organization and processing
allowing the calculation of the airflows. Comparisons are then made between the
model results and in one hand analytical expressions and in another and
experimental measurements in case of a collective dwelling. |
